I wanted a good SPO2 monitor, and heartrate monitor during exercise. If I push my heartrate up to 160-170 range the watch never figures it out. I tested this at the same time with another HR monitor. I do some Wim Hof style breath holding, and the algorithm never recovers if you hold long enough to lower saturation below %90. Lastly, when I get up in the middle of the night, I get false positive apneas from the app. It would be nice if the watch knew to mark part of the SPO2 data as ambulating. That would help eliminate false positives. I recorded times I got up and was awake so I could tell that there were false positives. I do like the product overall. I hope you find the information helpful. ### ⭐ Not worth it and poor customer service *by M***N on Reviewed in the United States on October 8, 2019* Watch was not as expected, pulse ox did not work most of time and when it did it was not accurate at all. contacted seller and they just told me what pulse ox was. screes will scratch with just your finger, found that out on the first day.Returning product and I have to pay shipping to even return it! Will NOT^ buy from this comapny again! ### ⭐⭐⭐⭐⭐ Love that it's cute and stylish ...do all that it said it did *by T***Y on Reviewed in the United States on November 14, 2019* I like that it's easy to set up and easy to connect --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/97005482-h4-v12-smartwatch-for-men-and-women-color-screen-ip67](https://www.desertcart.jp/products/97005482-h4-v12-smartwatch-for-men-and-women-color-screen-ip67) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-09*
